采自南海软珊瑚
Sarcophyton tortuosum
的内生真菌
Aspergillus
sp.在由葡萄糖10 g/L,蛋白胨5 g/L,酵母膏2 g/L,100%海水,pH为7.5的培养基(GPY)中能够产生真菌毒素青霉酸,产量为5.5 mg/L。在GPY培养基中添加200 mg/L的单萜α蒎烯,能改变代谢产物的组成和含量,并显著促进该真菌产生青霉酸,产量可提高至29.15 mg/L。结果表明α蒎烯在该菌的作用下主要得到系列氧化产物,并进一步发生氧化降解。单萜α蒎烯可以作为一个有效的诱导子,引起微生物的氧化应激反应,改变膜上酶系的活性,使代谢活动得到调控,改变代谢产物组成或产量,在微生物发酵工业上有潜在应用。
Fungus
Aspergillus
sp.
which was isolated from soft coral Sarcophyton tortuosum
could produce mycotoxin penicillic acid with the yield of 55 mg/L in GPY medium containing glucose 10 g/L
peptone 5 g/L
yeast extract 2 g/L
sea water 1 L
at pH 7.5 Interestingly
while the GPY medium supplied with αpinene at a dose of 200 mg/L
the constitute and content of the metabolites of Aspergillus sp altered obviously Furthermore
the yield of penicillic acid in the culture broth increased dramatically from 5.5 mg/L in control group (GPY medium) to 29.15 mg/L in biotransformation group Based on the gas chromatography mass spectrometry analysis
the major biotransformed products of αpinene were characterized as oxygenated monoterpenoids
which were undergone further biodegradation This finding suggested that monoterpene substrate
αpinene could used to be an elicitor It can alter the oxidase activities
trigger and modulate microbial metabolic pathways
and has potential application in fermentation
